An empirical rate equation was developed to predict head rice yield reduction for rough rice exposed to moisture adsorptive conditions. Time of exposure, initial moisture content, and relative humidity were significant to the reductions in head rice yield caused by moisture adsorption. An equation used to predict the number of kernels which fissured upon exposure to various environments was mod...

an experiment with randomized complete block design with 3 replications was carried out in the rice research institute of iran, rasht, during 2008 to study the effect of supplement foliar application of nitrogen (5% n) and potassium (3% k2o) at different growth stages (maximum tillering stage, booting stage, and both of them) on grain quality and nitrogen efficiency of hybrid rice, c.v. bahar-1...

In this study, we determined using NIRS the heritability percentage of amylose, protein, and moisture content in polished and unpolished rice in a CNDH population derived from a cross between Cheongcheong and Nagdong rice varieties. The results revealed a higher heritability percentage for the amylose content and compromised heritability for protein and moisture contents. We also conducted QTL ...

virulence of blastospores and conidia of the fungus metarhizium anisopliae were investigatedon different instar nymphs and adults of sunn pest, eurygater integriceps. experiments werecarried out through a factorial arrangement in a completely randomized design of threereplications. the bioassays were performed through immersion method. results revealedsignificant differences among virulence of ...

Analysis of generation mean was carried out in six crosses of rice viz., ADT 41 / ADT 46, ADT 41 / CO 47, ADT 41 /TKM 9, ADT 41/ Jeeragasamba, ADT 41/ACM 98003 and ADT 41/AS 90033 for hulling percentage, milling percentage, head rice recovery, kernel length, kernel breadth, kernel L/B ratio, kernel length after cooking, linear elongation ratio and alkali spreading value. The scaling test showed...

blast disease of rice caused by pyricularia oryzae is a potentially damaging disease in northern due to planting of susceptible local cultivars and favorable conditions. to assess the effects of blast on rice yield components and yield loss, one field experiment was conducted at the lowland culture conditions. analysis of blast effects on rice indicated that the maximum yield losses due to unpr...

Rice cold tolerance at the germination stage is important in Rio Grande do Sul (RS) where temperatures below 15°C prevent or reduce germination and plant establishment in early sowings. The present study aimed at identifying an adequate method for cold tolerance evaluation of the rice germination stage and at verifying the variability among 24 rice genotypes of different origins. Cold tolerance...
